5 Claims.

The present invention relates to sheet-metal roofing and roof structureand more specifically to a new and improved form and arrangement ofpartsby the use oi'whichan improved'roofstru'c- 'ture may be produced.

A 'largenumber of forms of heretofore been devised, but those which haveproved-commercially satisfactory have heretofore been "of complicatedconstruction. It is, therefore, a primary object of the presentinvention to provide a type of roof and roofing structure which isgreatly-simplifled bothas to manufacture and assembly.

A further object of the present invention is the provision "of a readily'demountable roof structure which is inexpensive to manufacture, andeasily assembled in the field by ordinary workmen without the needfor'speoial tools.

A further important object of the invention is the provision of a roofformed of panels detachably connected together to present a strong andrigid construction.

A further important object of the invention is the provision of aprefabricated panel forincorporation in a roof construction.

Astill further object of the invention is to provide an improved form ofridge member adapted to interlock with the upper portions of the roofpanels.

A still further object of the present invention is to provide animproved form of eaves structure adapted to have interfitting engagementwith lower portions of the roof panels.

Other objects of the invention will become apparent to those skilled inthe art from the following detailed description taken in connection withthe accompanying drawingswhich disclose a preferred embodiment of theinvention.

Figure 1 is a vertical sectional view of a'lower portion of the roof ofthe present invention;

Figure 2 is a plan view of the construction shown in Figure 1;

Figure 3 is a vertical sectional view of an upper portion of the roof ofthe present invention;

Figure 4 is a sectional viewof the construction of thereof at the gable;

Figure 5 is a sectional view 5-5 of Figure 1 Figure 6 is a sectionalview taken on the line 6-6 of Figure 1;

Figure 7 is a front view of a portion of the structural element forminga part of the roof panel; and

Figure 8 is a sectional view thereof.

Referring to the drawings, the roof is made up of aplurality of panels10 of novel construction. Asseen in Figure 6, each panel is made up withspecial structural elements termed modified C-shapes. Each 0-shape isformed of a web l2, flanges l3 and flange extentaken on the line metalroofing have herein sometimes :surface of the sheathing.

sions l-Ai-nclined at an acute angle to the flanges l3. An externalsheathing member 15, whichm'ay be of any desirable material butpreferably metal, is provided with flanges I 6 arranged'at an acuteangle to the plane of the sheathing member. A structural member ll istacked or integrated to sheathing member P5 in any suitable manner,preferably, if sheathing member i5 is forme'd'of metal, bye-line of spotwelding 'I 1 between flange l3 of the C-shape and the sheathing.Asseenin Figure 1, sheathing I5 isprovided at its lower edge with adownwardly inclined flange 18 having a reversely bent extension l9terminating in .a short section 20 spaced from the lower race-oi thesheathing member 'a distance equal tothe thick ness of the metal forapurpose to be later described. Theupper edge of the sheathing isprovided with a flange 2 l forming an angle with the In final assembledposition this is an acute angle (Figure 3:)

Figure 6 shows the: manner in which two adjacent panels are joinedtogether'to form a weather- 'tight joint. With the ends of the twopanelscontiguous and the O-shapes arranged with the web portions incontact, a spline or key member 22 having flanges disposed atangles'corresponding to the angles of sheathing flanges I6 is slid intolocking position as shown.

In Figure 4, a modified form of panel to be used at the gable ends ofthe roof is shown. In this form, the sheathing 23 has one edgeprovidedwi'th an upturned flange 24 .similar'to panel flange 16 in orderto receive a spline '22. The other edge of sheathing 23 has a downwardlydirected flange 25 secured to a gable member v215 by means of'sell-threadingscrews "21. As seen in this figure, additionalsecuringlneans in the form of spot welding I! may be used.

Referring to Figure 3, the ridge roll or cap 28, which extends thelength of the roof, is shownas being formed with a circular roll 29 andextending flange portions 30. Flange portions 30 are reverselybent toform rearwardly extending portions 3| lying against flange portions :30.Por- .tions 3-! are bent downwardly to form inclined walls 32 and thenforwardly to provide portions 3-3. The distance between portions 33 and31 is substantially equal to the thickness of spline member 22. Theangularity of inclined wall 32 :is

' complementary to the angularity of panel flange 2| in order that wall32 may lie against and contact flange 2|.

Referring to Figure 1, the space between the edge of the roof and thewalls of the shelter may be covered-by a specially constructed eavesmember 34 which may run the length of the roof The caves membercomprises a web portion having a depending flange 35 secured to wall 38by means of self-threading screws 31 and an upper flange 4| frictionallyreceived between flange 20 and the lower surface of sheathing member l5.

As shown in Figure 1, the roof supporting meanslcomprise a plurality ofchannel shaped horizontal beams 39. Each beam consists of a web rtion 40and upper and lower flanges M and 4 Self-threading screws 43 passthrough lower flange 42 and fasten the beam to channel member 44 forminga part of the wall structure of the shelter. The outer ends of thebeamsare suitably cut away to accommodate thesloping roof and inclinedeaves member.

The roof or the present invention i carried by a novel wall structureforming a separate invention disclosed in copending application SerialNo. 485,416, filed May 3, 1943, by the presentinventors.

In assembling the roof of the present invention, the beams 39 are laidacross thetop of the wall structure and secured thereto by screw 43. Theroof panels are then assembled as seen in Figures 1 and 3 by boltingtheweb portions l2 of complementary panels to each other by bolts 45 toform the sloping roof. The opposite ends of these web portions arebolted by bolts 46 to the ends of the corresponding beam 39. Splines orkey members 22 are then slid into position with the upper ends tightlyreceived in the space between flange portions 3| and 33 to form aweathertight joint between adjacent panels. The ridge cap 28 may then heslipped into position with flange 2 I being bent into snuglyengagingrelation with flange 32 a seen in Figure 3. The eaves membersare then applied by inserting flange 4| into the space between flange 20and the panel sheathing and securing flange 35 to the wall structure bymeans of the self-threading screw '31.

The roof may be taken down by merely reversing the above steps. I
